Gemini CLI Release Notes Highlight Changelog and Fixes

What happened

A new banner was added to indicate that the Gemini CLI is not optimized for Gemini 4. The README file was also updated to remove outdated content. Several bug fixes were implemented, including one to remove unsupported members permission in the unassign-inactive-assignees workflow.

Another fix addressed slash-command conflict deduplication by resetting it when conflicts reappear. A change was also made to verify active binary updates to avoid false success due to PATH shadowing. Support for the 'keys' array in the keybindings.json file was added, and a fix was introduced to forward termination signals from the bootstrap parent to the child process.

Why it matters

These updates improve the stability and reliability of the Gemini CLI, ensuring users are aware of compatibility limitations and can benefit from enhanced workflows. The inclusion of a full changelog aids in tracking changes between versions, which is critical for developers maintaining or integrating the tool.
